As the sixth annual Rocky Mountain Audio Fest draws to a close at the Denver Marriott Tech Center, what is now the largest annual audio show in the USA could boast an attendance of 3700, 200 more than last year. Prominent among attendees from 49 states and overseas was a notable increase in the number of under-40 attendees. No doubt they were drawn by the rise of audiophile computer-audio playback, the resurgence of vinyl, and the large exhibit hall populated by the Head-Fi headphone community. The younger attendees included an influx of students, who responded to RMAF’s concentrated outreach to local colleges.
